CI: Test on macOS 11.0 Big Sur

[traversaro]

See actions/runner-images#1814 for more details on the environment.

CI is successful on the first try, ready for review, tagging a few mac users @lrapetti @CarlottaSartore .

@traversaro I am not anymore a mac user, I switched to Ubuntu :)

Good to know, thanks!

FYI, brew is not happy with the default Xcode on macos-11.0 (11.7)

I had to change it with this command:

sudo xcode-select -s /Applications/Xcode_12.3.app/Contents/Developer

You can check which versions are installed running

ls -n /Applications/ | grep Xcode*

Why even without that fix, the CI on Big Sur is working fine?

I think that you are either not using brew, or perhaps all the formulas use bottles?

For reference, the output of the ls command is this:

You can probably exploit this also to test different Xcode versions...

[drdanz]

The error I had seems to appear when I install YCM which does not have a corresponding bottle...

[traversaro]

perhaps all the formulas use bottles?

I think this is it.
